The automobile wiring harness is the main body of the automobile circuit, and there is no automobile circuit without the wiring harness. As people’s requirements for safety, comfort, economy, and emission of automobiles increase, automobile wiring harnesses become more and more complex, but the space for wiring harnesses in automobiles is getting smaller and smaller. With the development of the automotive industry and the improvement of design concepts, the requirements for the use and performance of tapes for wiring harnesses of different functional parts have appeared diversified, and the market size of automotive wiring harness tapes has been increasing year by year. As automotive wiring harness tape still has high technical limitations, from the market point of view, automotive wiring harness tape is highly monopolized in many places. With the deepening of the automotive industry chain, the demand for wiring harness tape will further increase. For new products , Will be a good opportunity to cut in. Wire harness tapes are generally divided into three types: PVC tape, air flannel tape and cloth tape. PVC tape has better abrasion resistance, flame retardancy, poor noise reduction, and lower price. The material of flannel tape and cloth tape is PET. Flannel tape has the best wrapping and noise reduction properties. The cloth tape has the best abrasion resistance.
